Tannin Bleed & Stainblocking: After priming, test for 
stain bleed-through by applying the top coat to a small 
section. If the stain bleeds through the top coat, apply a 
second coat of primer and test again before top coating 
the entire area. If bleeding continues, a longer dry time 
of the primer may be needed before topcoating or an 
additional coat of primer may be required to block the 
tannin bleed or stain.
Masonry: Stucco, Concrete, Cut Masonry Units (CMUs), 
Split-Face Block: New: All masonry surfaces must be 
cured at least 30 days before painting. The pH must be 
10.0 or lower prior to coating. Smooth masonry may 
require an adequate prole for adhesion. For all other 
smooth concrete, create a prole using a product such 
as a muriatic acid etcher or with mechanical means. Remove 
loose aggregate and debris.
Masonry: Cement Composition Panels/Siding, 
Exterior Insulation and Finish Systems (EIFS) or 
Synthetic Stucco: New: All masonry surfaces must be 
cured at least 30 days before painting. The pH must be  
10.0 or lower prior to coating. All surfaces must be clean,  
free of dust, chalk, mold and mildew stains, loose and 
peeling paint and all other foreign substances. Clean surfaces 
with a detergent and water solution by scrubbing the surface 
vigorously and rinse with a garden hose or a power washer at 
a low setting (500-1200 PSI). DO NOT USE HIGH PRESSURE as 
this may harm the substrate.
Previously Painted Surfaces: All surfaces must be clean, 
free of dust, chalk, mold and mildew stains, loose and 
peeling paint and all other foreign substances. Clean surfaces 
with a detergent and water solution by scrubbing the surface 
vigorously and rinse with a garden hose or a power washer 
and allow to dry.
